Really bad seeing in this ocassion. I tried to overcome it by recording long captures, but still not big success. Besides, bad data requieres so much more effort than good data. IN special, cleaning "ringing effects in the craters". Well, I guess that if the image is not viewed at full res, it may have a go. Although a bit "too washed" or soft for my liking....

Nevertheless, if you cant be a great image, at least have a good story.... and there is plenty of elements in the image for interesting facts!

To start with Rupes Recta  with lengths  around  120 km  and a difference in height between  the eastern and western sides  amount to between 250 and  300 m, with a width of about  2.5 to 3 km. This gives a gradient of less than 10°, so Rupes  Recta is rather a gentle slope  and not,  as the spectacular  shadow might imply, a steep  escarpment or a fracture. The slope was probably created by a subsidence  of the western side, the crater  Birt side, of Mare Nubium, initiated by shock waves from the  Imbrium impact and later altered and deformed by the Mare  Nubium lava flows. 

Over Rupes there is Thebit crater, 56 km in  diameter with terraced walls. The below Rupes, there is Birt, a small, circular and funnel-shaped crater, 16 km in diameter,  with the craterlet Birt A (6.8 km) breaking the eastern wall.  Rima Birt a linear rille, runs for a distance of  about 50 km, approximately parallel to Rupes  Recta. It is badly seen in the image though.  

Now let us go for the big ones, Alphonsus,  one of the most interesting  craters on the nearside of the Moon, and Arzachel, of which I already wrote a long entry in this image https://www.astrobin.com/s2ji4e/

On the right side of the image, there is Purbach directly adjoining the northern crater wall of Regiomontanus, and Deslandres, which with its diameter of 256 km,  is one of the largest craters on the nearside  of the Moon. Its crater wall  is broken on the south by Lexell and in the east by Walther. It  formed in the Pre-Nectarian  Epoch (between 4.5 and 3.92  billion years ago), and it is  so eroded that it was not given  its own name in early Moon  maps. Cassini's Bright Spot (one of the  brightest spots on the Moon’s surface ) is also in Deslandres, but unfortunately is not well appreciated in this image.
